The present invention relates to thin stone or thin brick veneer wall systems and to clips for fastening facing elements thereof.
Brick veneers are typically constructed by using thin bricks or a stone tiles and fastening them to a wall and panel with the aid of an adhesive. Brick veneer construction is often less costly than full brick construction because it does not require a skilled masonry tradesperson, it also does not necessary require the building of a foundation for support. Thin bricks for thin brick veneers can be made of stone, polymer materials or composites of polymer and cement. Others thin brick veneers are made by splitting cement blocks and dressing the front face. Polymers and polymer composites often lack the appeal of natural brick and may not be preferred by some customers because of aesthetic reasons. Cement thin bricks are more similar in appearance to natural stone bricks but quick construction of a thin brick veneer wall does require one to be knowledgeable in masonry methods.
Thin brick systems using adhesives may be less secure due to improper application. Additionally, over time some adhesives may not hold as well when exposed to certain weather conditions which can lead to loose or falling bricks.
There are a number of methods and devices of affixing thin brick veneers, however they often are complicated and do not provide any methods for water drainage. Some brackets and clips required for installing thin brick veneers require much time consuming work thereby negating the supposed quick and easy installation advantage of the thin brick veneer system.
Canadian patent CA 2526876 issued to Huff and Shouldice, discloses a thin brick system which clips to attach bricks to a wall. The system is comprised of two types of clips which are housed within a groove in the lower edge of the upper stone and within the groove of the upper edge of the lower stone. The system requires individual clips to be nailed to the wall. This system also does not contain a wall gap that can serve as a water channel on in which foam insulation can be sprayed. Additionally the bricks do not contain the different length extrusions that allow for fast mounting of the brick as in the present invention.
U.S. Pat. No. 4,809,470 issued to Bauer et al., discloses a structure and a method for construction of a brick facade. It comprises of a panel that is configured to secure bricks by using a friction fit and the rear surface of the brick is secured using an adhesive. The present invention does not use any adhesive materials in its implementation nor does it require the mounting of panel for installation of the bricks.
PCT/IB2004/050464 filed by Passeno, discloses a panel made of sheet material that has rows of spaced block support elements in the form of prongs. The blocks rest on the prongs and the gaps left by the blocks can be filled with mortar. This invention does not have the ability to be mounted to wooden studs to allow for a water channel or for a space to allow foam insulation to be sprayed. Additionally, the invention also requires a large panel to be fitted and installed unlike the present invention which uses C-bars which can be more easily fitted to differing wall lengths.
There is a need to improve thin brick veneer system so as that they do not require addition of adhesive materials and allow for a simple mechanical installation. Some of the disclosed prior art requires the use of adhesive to secure the bricks to the panel or wall. This steps requires additional materials and additional time for construction of the veneers. Other systems in the prior art require installation of large panels for which have to be sized and cut to fit the wall. This may be difficult and time consuming for large sized panels. Additionally, none of the systems in the prior art provides a means for constructing a water channel or space for the addition of foam insulation in its design. The present invention provides a quick method of mechanically attaching brick veneers that requires less material than previously. It also increases the functionality of thin brick veneers by adding a water channel and means for installing foam insulation.
The first objective of the invention is to provide a quick, efficient and inexpensive method of creating brick veneers. Most brick veneer systems require a type of adhesive or extensive methods for securing the brick to the wall or panel. The present invention uses a horizontal C-bar that can be fitted to a length of the wall to allow for bricks to be mechanically and easily placed.
The second objective of the present invention is to improve upon existing thin brick system so as to provide added insulation and the ability to improve water drainage. For this purpose, the present invention separates the brick veneer system from the wall with a series of wooden studs. The studs serve to secure the C-bar and provide a gap between the wall and the brick veneer. This gap can then be filled with foam insulation or left empty to serve as a water channel.
A third objective of the present invention is to provide a mechanical means of attaching natural stone or tiles. Another embodiment of the present invention has the C-bar edges oriented at a narrower angle which function to hold natural stone or tiles and has elements like grout or other filler in addition to cement that can be placed in the gaps of the tiles.
The present invention is a thin stone or thin brick wall system comprising: a plurality of stone or brick facing elements, a plurality of steel C-bars housed on wooden studs, the wooden studs being housed against a plywood board. The gap between the wooden studs can be used as a water channel or foam insulation can be sprayed into the gap. The C-bar is attached by nails to two wooden studs. The C-bars are horizontally separated approximately a brick height.
The thin bricks of the present invention have three grooves along the length of the brick. The bottom and top grooves have further extrusions or channels that aid in attaching the brick onto the C-bar. As the bricks are attached to the C-bar a consistent gap is created between each brick or tile. The gap between the bricks can be filled with cement or other type of filling material.
Other embodiments include using natural stone or tile instead of thin bricks. In this embodiment, the C-bar edges are designed at an angle that is less than 90 degrees. The appropriate stone or tile has grooves that match the angle of the C-bar edges for easier insertion.
The present invention has two general embodiments of the C-bar. A conventional steel C-bar which has an appropriate height that it is able to have attached two thin bricks. Its depth away from the wall is such that thin bricks can be flatly placed against it, and two edges of a differing length which are designed to hold the thin bricks. The top edge is of a shorter length than the bottom edge. The differing lengths of the two edges are designed so that a groove of the thin brick can easily fit the shorter edge, allow it to be raised and the bottom of the brick can be inserted into the lower edge of the upper C-bar and be held there.
The second C-bar is designed for either the top or bottom of the brick veneer. One end contains the long edge as described above and the other end is flat so as to support the bottom of the thin brick or tile. The flat end extends to cover the bottom of the thin brick.
Embodiments herein will hereinafter be described in conjunction with the appended photos provided to illustrate and not limit the scope of claims, wherein like designations denote like elements, and in which:
A detailed view of the specialized bricks 100 is shown in
a shows how the bricks 100 are attached to the wall via the C-bar 300. The bricks 100 are attached to the C-bar 300 via the channels 101-102 in the extrusions. A brick 100 is attached at the top channel 101 to the bottom end 302 of the upper C-bar 401 and at its bottom end channel 102 to the top end 301 of the lower C-bar 402. The C-bar 300 is connected to a wooden stud 405 by a nail or screw 404 that is inserted in through one of the holes 303 of the C-bar 300. The wooden studs 405 themselves are connected to the wall by either nails or screws.
b shows that there are also C-bars which are used at the top and bottom of the veneer. The end C-bars are modified forms of the regular C-bars. The top end C-bar 410 contains one end 411 which runs straight and perpendicular to the wall and the other end 412 contains regular extension as a regular C-bar. The bottom C-bar 420 contains an end 421 which runs straight and perpendicular to the wall and the other end 423 contains a regular long extension as a regular C-bar.
The preferred embodiment of the end C-bars, 410 and 420, the panels are 24 mm in height. One end extends to a depth of 8 mm and turns downward to a length of a further 8 mm. The opposite end extends to a depth of 12 mm and remains flat.
The design of the panels and bricks allows for a consistently sized even gap 501 between each layer of bricks. The gap or space 501 between the bricks 100 can be filled with cement, mortar or other similar type of building material. The filler will serve to further strengthen the attachment of the bricks 100 to the panel 300 and prevent any vertical motion of the bricks.
Other embodiments of the system include a bar for placing natural stone or tiles.
As common materials for making tiles and natural stone are generally more brittle it may be difficult to extrude portions of the tiles and natural stone as is done with the thin bricks 100. The tiles or natural stone pieces 700 and their method of installation is shown in
c shows that installation occurs by placing the top end of the brick 801 on the bottom end 812 of the C-bar 810 and then pressing the bottom end 802 of the brick to the top end of the second C-bar 810 until the brick is secured.
Natural stone can also be installed using an alternative method. The C-bar 915, shown in
The forgoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
With respect to the above description, it is to be realized that the optimum relationships for the parts of the invention in regard to size, shape, form, materials, function and manner of operation, assembly and use are deemed readily apparent and obvious to those skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.
